[dependabot]

Bumps sanitize-html from 1.20.1 to 2.8.1.

Changelog

Sourced from sanitize-html's changelog.

2.8.1 (2022-12-21)

• If the argument is a number, convert it to a string, for backwards compatibility. Thanks to Alexander Schranz.

2.8.0 (2022-12-12)

• Upgrades htmlparser2 to new major version ^8.0.0. Thanks to Kedar Chandrayan for this contribution.

2.7.3 (2022-10-24)

• If allowedTags is falsy but not exactly false, then do not assume that all tags are allowed. Rather, allow no tags in this case, to be on the safe side. This matches the existing documentation and fixes [issue #176](apostrophecms/sanitize-html#176). Thanks to Kedar Chandrayan for the fix.

2.7.2 (2022-09-15)

• Closing tags must agree with opening tags. This fixes [issue #549](apostrophecms/sanitize-html#549), in which closing tags not associated with any permitted opening tag could be passed through. No known exploit exists, but it's better not to permit this. Thanks to Kedar Chandrayan for the report and the fix.

2.7.1 (2022-07-20)

• Protocol-relative URLs are properly supported for script tags. Thanks to paweljq.
• A denial-of-service vulnerability has been fixed by replacing global regular expression replacement logic for comment removal with a new implementation. Thanks to Nariyoshi Chida of NTT Security Japan for pointing out the issue.

2.7.0 (2022-02-04)

• Allows a more sensible set of default attributes on <img /> tags. Thanks to Zade Viggers.

2.6.1 (2021-12-08)

• Fixes style filtering to retain !important when used.
• Fixed trailing text bug on transformTags options that was reported on [issue #506](apostrophecms/sanitize-html#506). Thanks to Alex Rantos.

2.6.0 (2021-11-23)

• Support for regular expressions in the allowedClasses option. Thanks to Alex Rantos.

2.5.3 (2021-11-02):

• Fixed bug introduced by klona 2.0.5, by removing klona entirely.

2.5.2 (2021-10-13):

• Nullish HTML input now returns an empty string. Nullish value may be explicit null, undefined or implicit undefined when value is not provided. Thanks to Artem Kostiuk for the contribution.
• Documented that all text content is escaped. Thanks to Siddharth Singh.

2.5.1 (2021-09-14):

• The allowedScriptHostnames and allowedScriptDomains options now implicitly purge the inline content of all script tags, not just those with src attributes. This behavior was already strongly implied by the fact that they purged it in the case where a src attribute was actually present, and is necessary for the feature to provide any real security. Thanks to Grigorii Duca for pointing out the issue.

2.5.0 (2021-09-08):

• New allowedScriptHostnames option, it enables you to specify which hostnames are allowed in a script tag.
